okay, I'm not woo hooing anymore! I've done nothing but stay in the bed since Wednesday. I got out a bit Thurs was absolutely worn out and came home. Was going to get my grandbaby Thurs. evening but not enough energy. I don't know if there are side effects of the B12 or it's the new medications for high cholesterol. I also have a headache. I probably should have called the dr. but I didn't wake up in time to do so this afternoon and I kept thinking she said in a couple of days I'd feel better. I don't know if it's depression or side effects. I don't think it matters, or does it?
